Visiting the Natural History Museum you can be fascinating by all the amazing minerals and gemstones. There are some examples of mineral use, ornamental mineral art and meteorites.
The best place to find minerals is at mines. Mines are locations where industrially important rocks, minerals and gemstones are extracted from the earth.
Mines can produce large amounts of specimens of certain minerals, and continue to provide specimens as long as the mine is actively working. Some are also found in road cuts on the side of roads, highways and railroads.
A part from this there different gemstones marvel at variety of colours, textures and shapes. One of the most important diamond in the museum is the Cullinan.
Discovered in 1905 at the Premier mine near Pretoria, South Africa, it is the largest diamond ever found (3106 carats), although its shape suggest that it was part of an even larger stone. It was purchased by the Transvaal and presented to King Edward VII on his birthday and cut in 9 diamonds and in 96 small brilliants. Glass models of the nine cut are shown in the museum, while the 4 largest stones are in the Crown Jewels of the United Kingdom.
The Great Star of Africa (530.2 carats), reputed the largest and most perfect diamond in the world and now in Queen’s Sceptre with the Cross.
It measure 58.4×45.4×27.7 mm, and has 76 facets. Other diamonds are: the Second Star of Africa (317.4 carats) now in the Imperial State Crown; the third star of Africa (94.45 carats) and the Fourth Star of Africa (63.65 carats) both now in the queen’s possessions.
Today, the Cullinan is situated in the tower of London. The years pass and the earth creates spectacular things and minerals, but a diamond is forever.
